The HVAC Quality Installation Specification (ANSI/ACCA 5 Q1-2007) that has been developed and published by the Air Conditioning Contractors of America (ACCA) as part of an Approved American National Standards

Part 2 of Jim Wheeler's AHR Expo coverage.

In Part I of Jim Wheeler’s coverage of the show, he discusses refrigerants and plumbing and bath products. More of his observations will follow in Jim Wheeler’s regular monthly HVACR columns published in SUPPLY HOUSE TIMES.

I was shocked and appalled at the state of our industry when I read the news item in the December 2006 issue of Supply House Times (page 24) “Emerson Survey Shows Most Of 10 SEER Inventory Installed,” for it told of how supply houses and contractors alike had stocked up on 10-SEER residential air-conditioning units so they would have something cheap to sell.

This heat pump creates more heat on extra-cold days with a second compressor and a special heat exchanger.

Don''t risk the customer''s compressor with sloppy measurements.

It's good for business to have at least one person behind your parts counter who really knows the business and can give good advice.

Just a little trivia for you: It was sometime in the 1960s, I believe, that a few of the first residential air conditioners were shipped from the USA to Japan.

I had a call from a marketing lady last October (I often get such calls) who wanted to pick my brain as to what would happen when our industry had to provide residential air-conditioning units with a minimum of 13-SEER efficiency. She didn't tell me who she represented or why she was asking. I thought you might be interested in my reply.

Because many of my articles in SUPPLY HOUSE TIMES can be found by Internet search engines, scarcely a week goes by when I don't receive a question from a consumer asking an HVACR question that he or she has taken the time to research on the Web.
